  • Henrietta Swanlevitt

    • Observed a linear relationship between the luminsoity and the pulsation period of a star. Pulsation period: The time it takes for a cepheid star to alternate between its brightest to its dimmest and back. Luminosity: The measure of brightness of a star Cepheid: A member of a class of luminous variable stars.
